It's supported, sometimes there are sync issues and you need to remove and reapply the BFD configuration.
Have you consulted the configuration guide?

please attach a text file with the outputs on both routers for:
show run interface
show interface
show run | s router bgp
show bgp ipv4 unicast neighbor [ip]
show bfd neighbors details
also, are you using any kind of redundancy? like dual sup, or chassis or something else?
regards.
